IMPROVEMENT IN IRON PLOW-BEAMS.

The schedule referred to in'these Letter Pa.teut and mking of the sama.

To all whom it may concern Be it known that I, ALBERT BALLFof Cant-on,

-Stark county, Ohio, have invented certain new and useful Improvements in Iron-Beanillows, and that the following 1s a full, clear, and exact specification o f my said invention.

Nature and Object of my Invention.

My invent-ion relates to the construction of a peculiarly-formed metal plow-beam, and to the combination of said beam with the mold-board, share, and land-side, said beam being of such a form that a transverse section of the same at any point shall be of a U-shape, 'and that the vertex of any such scctiou shall be on the lower or anterior side ot' the beam and the open part on the upper or posterior side of said beam, and the lower A'end ot' said beam forming the standard for the plow, upon which the mold-board, share, and land-side are fairly seated, and to which they are secured by suitable clamping-bolts without the interposition of any intermediate supports between the beam By this construction I obtain a combined beam and standard which can be made with much less material for the 'same strength than any of the old forms of plow-beams, as its forni is such that its lower end is of just the proper shape to allow the mold-board, share, and land-side to be bolted directly toit, so that no extra material is required to form flanges for the attachment of any of said parts or to form intervening supports between the beam and saidl parts, while the arrangement of the material in the beam is such as to give it greatv stiffness against any strains which maybe brought to bear on it.

Description of the Accompanying Drawing. Figure 1 is a plan of a plow embodying my invention.

Figure 2 is a side view of the same taken from the mold-board side.

Figure 3 is a side view of the same taken from the' land-side.

Figure 4 is a side view of the plow-beam taken from the mold-board side.

y General Dcscrtption.

and then extends forward as shown to form the forward portion A, which is the beam proper. aThe transverse section of the beam at any pointis of a U-form, as shown inV plan in fig. 1 and by detached sections on the lines uc, ad, and w z, in gs.

,2, 3,' and 4; and it will be seen that the form of section is slightly varied at different points ou the beam, and that the cross-section gradually diminishes in size from the base E to the end of the beam A, the sections of the lower end of the beam having a sharp vertex, as shown by the section b a b, on the line w z', in fig. 4, so as to obtain the propel' .seats for the mold-board, share, and land-side, and the sections on the standard portion B and beam portion A having a more rounded vertex, as shown by the sections b a b,

o u the lines c ll and u c, in figs. 3 and 2, so as to obtain the proper lateral stiffness to resist the side strains from the draft. It is als seen that in any transverse section of the bea-m portion A, as, for example, the section b a l), on the line u fu, iu lig. 2, the vertex a of said section is on the lower side and the open part b b is on the upper side of said beam, and that in any transverse section ofthe standard portion B, as, for example, the section b a b, on the line c d, in iig. 3, or the section b a b, on the line w z, in iig. 4, the vertex a is on the anterior side and the open part is ou the posterior side ot' the beam, so that any transverse section ofthe beam is of a U-form, and has its vertex on the lower or anterior side' ot' the beam and its open part on the upper o1' posterior side of the beam.

The mold-board H is laid on its seat C, on the face of the beam, and is secured in that position by the bolts T l, which pass through holes in the mold-board and side of the beam.

The land-side Gr is laid and secured on its seat F, on the face of the beam, by the bolts Q, Q, in a similar manner, and the share I fits down on its seat D, ou the face of the beam, in front 0f the mold-board and land-side, and has a square offset on its under side which abuts against the point Y of the beam, the share being held in this position by the bolt W, which passes through a hole in the share and a corresponding hole in the beam. The brace-bar L is secured between the mold-board H and land-side G by the rivets S S, and serves to prevent the mold-board and land-side from springing together at their rear ends.

lhe handle-standard M is secured on the brace-bar L, and the handles J J are united at their lower ends, and are pivoted by a bolt, O, to one eide of the beam', from which they extend back ou each side of the standard M, as shown in fig. 1, and are united near their upper ends by the crossbar K.

The bolt N passes through the' handles J J, and

through the slot Rin the standard M, so that said handles can be clamped to the handle-standard at any desired height, as isrcadly seen.

From the foregoing description of the construction of my improved. beam audits attachments, it is evident to any mechanic that the beam can be madeof cast or malleable iron, or of wrought-iron or'steel, as may be desired, and that the mold-board, share, and land-side can bc made of cast-iron or of steel, or one or two of them may be made of cast-iron and the others of steel, the form of the parts being the same in either case.

I am aware thatxnetal plow-beams have been before constructed of a U-shaped section, as shownin Il. Ball, Jr.s, patents of February 14, 1865, and June 11, 1867, but in those constructions the vertex and open parts of the transverse section were on the vfurrow side and land-side of thebeam, respectively "instead of being on the lower or anterior side and upper or posterior side of the beam; hence there was no face of the beam to which the land-side could be att-ached, and itwas necessary lto provide an additional auge at the rear and lowerpart of the beam in order to obtain a proper attachment for the lalidf side, whereas, in my improved form of beam, uo sach additional Harige is necessary, as the side ofthe beam is in just the proper position toallow the land-side to be bolted directly to it. I am also aware that wroughtiron plow-beams have been constructed of a U-shaped section, and with the vertex and open parts of the sections ou the upper or posterior side and the lower or anterior side of the beam, respectively, as shown 'to serve as the direct surface of attachment for each and all of the parts'.

I disclaim both of these old and different forms ot ,metal plow-beam, and confining myself to the particular plan of construction herein specified,

WVhat I claim as new and of my invention, and dc- ,sire to secure by Letters Patent, is-f- The metal plow-beam A B, constructed of such form 'that a transverse section of the same at any point shall be of a U-shape, and that the 'vertex of any such section shall be on the lower or anterior side of the beam and its open part on ,the upper or posterior side of the beam, the lower end of said beam having the faces ,0, D, and E, on which the moldboard, share, and `land'side are placed, and upon which. they are secured by bolts passing through the sides of the beam, substantially as is herein specified.

As evidence that I claim the foregoing I have hereunto set lnyhand, in the presence of two withesses, this 12th day of January, A. D. 1870.

ALBERT BALL.
